What we offer

The General Accountant will be a key contributor within a growing and collaborative finance team, supporting the financial operations of a dynamic and evolving manufacturing start-up.

The General Accountant safeguards the integrity of the books and supports a disciplined month-end close, with hands-on ownership of journal entries, balance sheet reconciliations, bank reconciliations, fixed asset accounting, HST/indirect tax compliance, audits and year-end activities. In our scaling manufacturing environment, this role partners with Cost/Operations to keep inventory subledgers, WIP, and variances accurate and auditable, and helps mature our ERP-driven control environment as we scale.

What you’ll do

Month-End Close & General Ledger

• Prepare and post journal entries (accruals, prepaids, deferrals, intercompany); maintain close checklists to hit calendar deadlines. Own balance sheet reconciliations (cash, AR/AP subledgers, inventory, prepaids, accruals, payroll-related accounts), ensuring reconciling items are cleared promptly.
• Perform bank reconciliations and daily cash postings;
• Contribute to quarterly and annual financial reporting packages and supporting documentation.

Fixed Assets & Capex

• Maintain the fixed asset subledger; apply capitalization policy and start depreciation accurately; reconcile to the GL monthly.
• Support capex governance: ensure POs/invoices align to projects, commissioning dates, and asset tags; prepare CIP to FA transfers

Inventory & Cost Accounting (Manufacturing)

• Partner with Operations/Cost Accounting to keep inventory subledgers (Raw/WIP/FG) and WIP accurate;
• Support standard cost updates, BOM/routing changes, and variance analysis (PPV, usage, rate/efficiency, OH absorption). 

Tax & Compliance

• Support in the preparation and filing of tax returns; reconcile transactions to the GL/subledgers; maintain evidence for audits. 

AR/AP & Cash

• Provide backup/oversight for AP/AR (3way match, credit memos, aging reviews).
• Assist with intercompany settlements and confirmations (if applicable). 

ERP, Data & Process

• Become a power user in the ERP (Odoo experience is an asset);
• Drive automation and document SOPs/controls as the business scales.

Other duties as assigned

What you bring

• Bachelor’s Degree, with a specialization in Finance or Accounting, CPA (completed or in progress) preferred.

• Advanced analytical ability with strong Excel proficiency; able to interpret complex data and deliver clear, actionable insights.
